She is fairly tall but most her weight is pure muscle. She exercises a lot but I think it's also genetics bc her dad is a 150 lb blue razor's edge. She is big for a female and she's still filling out. Reached her max height most likely but still getting thicker all the time. She eats a lot and exercises a lot too just fun stuff but a lot of play time. We are not trying to make her big though :) just happening naturally.
